Benefits of technology

The present invention provides a way to make sure that magnetic devices made with high-temperature materials are always cooled properly without requiring too much expensive liquid nitrogen. This makes them easier to use and assemble, which can save money and simplify their operation.

Problems solved by technology

This patent discusses how much it costs to operate and make superconducting magnets due to the high price of helium, which they require. There are technical needs to reduce these expenses by finding ways to lower production and maintenance costs while still achieving effective results with the magnets.

Embodiment Construction

[0017]Aspects of the present invention have been shown to offer advantages over previous methodologies of cooling superconducting magnets. The apparatus and method require no mechanical moving parts (e.g., no pumps, no external pressure fed supply system, no refrigeration “coldbox” for cryogen supply, no helium can-fed flow, etc.) in cooling a superconducting magnet. The cooling method is orientation-independent, which aids in the design and ultimate physical volume and footprint of the superconducting magnet assembly. Design integration of tubing into the existing superconducting magnet geometry is simplified. Further, any hot spots that may arise can immediately be cured by the pulsating slug flow provided by the pulsating heat pipe employed in aspects of the present invention. The design offers other advantages in that it does not require costly helium bath cooling, nor is any cryogen lost during a quench. The proposed capillary tubing can withstand high pressures of several 100 ...
